(54) | Methods for making electron emission device and image forming apparatus, and apparatus for making the same |
(57) A method for making an electron emission device, which includes a conductive film
having an electron emitting section disposed between a pair of electrodes, includes
a removal step for removing impurities in an organic substance, and a voltage-applying
step for applying an voltage to the conductive film through the electrodes in an atmosphere
containing the organic substance. The electron emission device is suitable for an
electron beam source in an image forming apparatus. |
